The actress credits Proactiv for her smooth complexion (she’s the company’s newest spokeswoman), but admits her face wasn’t always so flawless.

“I had major skin problems as a teenager,” she admits. But once she started using Proactiv’s products 10 years ago, “my life changed for the better,” she says. “My family used to say, ‘You should be the spokesperson!’ since I was always saying how much I loved it.”

Though the actress is clearly excited to be partnering with the brand, you would think someone so public wouldn’t want to admit to having flaws. But Cuoco’s reasoning is clear: “I want people to know that ‘celebrities’ and people in the public eye are not perfect,” she shares. “Many struggle with skin issues. I wanted them to know how much this product could change their life, as it changed mine.” Tell us: What products do you use to keep your skin glowing?
